Sephora's Spring Bonus sale starts on April 13 for members of its Beauty Insider rewards program.

VIB Rouge members will get 15% off their entire purchase on April 13 - April 16 and April 20 - April 23.

VIB members will get 15% off on April 20 - April 23, when Insiders will get 10% as well.

Gift sets are a great way to get the most bang for your buck during the sale, since they are already good value before they are discounted.

Customers are limited to one Dyson product and three Drunk Elephant products per purchase; products from the online-exclusive brand The Ordinary are not available as part of the sale.

It's one of the most wonderful times of the year: Sephora is about to have its Spring Bonus Sale, during which you stock up on all of your favorite makeup and skin-care essentials while feeling up to 15% less guilty about it.
